Abstract

Pour protéger les coussinets qui soutiennent les tourillons d'engrenages de pompage, des paramètres opérationnels restreints sur la base de la température sont fixés pour des pompes hydrauliques à engrenages. En général, de telles pompes ne fonctionnent pas à des températures supérieures à environ 210 ·F. Il est toutefois nécessaire d'obtenir des pompes hydrauliques à engrenages capables de pomper un fluide hydraulique à des températures pouvant atteindre environ 250 ·F sans endommager les coussinets. Pour pomper un fluide hydraulique à ces températures, le procédé de l'invention raccorde la canalisation de retour du système dans lequel fonctionne la pompe à une chambre de graissage à une extrémité d'un tourillon soutenant un des engrenages de pompage. Le fluide hydraulique refroidi par l'échangeur de chaleur est ensuite aspiré à basse pression dans une zone de dépression d'un orifice d'admission de la pompe, à travers une interface située entre les coussinets qui soutiennent les tourillons de l'engrenage et les tourillons de l'engrenage eux-mêmes. Ainsi, les coussinets et les tourillons de l'engrenage sont graissés avec un fluide hydraulique dont la température est sensiblement inférieure à celle d'un fluide hydraulique contenu dans une canalisation de retour ou dans un réservoir.
